Title: Automatic actuation of a brake system in addition to and in connection with the usual, manual actuation by way of a brake pedal, achieved by a hydraulic actuating cylinder with associated circuit and control
IPC: B60T13/14
Filed: 1987-10-19
Abstract: The now usual antilock brake systems for motor vehicles are actuated exclusively manually by way of the brake pedal. The hydraulic actuating cylinder is an actuating unit inserted between the brake pedal and the antilock system which automatically actuates the antilock system. This automatic actuation comprises a special hydraulic cylinder with loose piston and piston rod passing through this, which piston rod can be connected on the one side to a brake pedal (for example passenger cars, trucks, buses, etc.) and, on the other, to a usual antilock system. The piston rod and hence also the coupled antilock system are actuated either manually by the coupled brake pedal or (or alternatively simultaneously) by the application of hydraulic pressure to the loose piston by way of a hydraulic circuit, which is controlled by a computer. Controlled by the computer, therefore, a motor vehicle can be braked automatically, but alternatively either manually or simultaneously.

Patent DE-3807160-A1 (DE)
Title: Arrangement for inspecting and separating coins
Inventor: GUINDULAIN VIDONDO FELIX
IPC: G07D/
Filed: 1988-03-04
Abstract: A coin inspecting and separating arrangement is indicated, such as is used in automatic vending machines, gaming machines and the like. The inspecting arrangement and the separating arrangement are combined with one another in such a manner that, when a coin is judged to be acceptable, a coil is activated, which opens a coin duct which for unacceptable coins is closed by a small plate which can be drawn back by a coil and which conducts the coins into a return compartment in the unexcited state of the coil. Arranged below the small plate is a second small plate, onto which the accepted coins fall and which can be drawn back by a second coil in order to open a second duct, but in the unexcited state of the coil conducts the coins further into a duct in which they are subjected to further sorting. Arranged in this further duct is a further plate which can be drawn back by a third coil in order to open a duct which leads to a coin receiving region. If the second and third plates are in their closed position, the coins roll into a collecting container. With the arrangement described, at least two different coin types can be separated from all the rest out of a large number of different coin types.

Patent DE-3829357-A1 (DE)
Title: Logarithmating analog/digital converter
Inventor: PLASBERG GEORG
IPC: H03M1/62
Filed: 1988-08-30
Abstract: In this converter, the logarithmation is produced by comparing the input voltage and two reference voltages with the voltage across a capacitor which is discharged via a resistor. The digital output word is formed from the time differences between equality of the discharge voltage of the capacitor and the input and, respectively, the reference voltages with the aid of a counter and of an oscillator controlled by a phase-locked loop. The invention is capable of replacing the previously used cascade circuit of an analog logarithmator and of an analog/digital converter and, compared with the analog logarithmator, offers the great advantage of a basic temperature independence of the transmission characteristic which renders superfluous a temperature compensation or a thermocouple. In addition, no calibration is necessary. A circuit, which is very inexpensively implemented in accordance with the method described, has an input-voltage range of 60 dB and an accuracy of better than 0.68% RTI. This accuracy approaches the limit of what can be achieved with a conventional logarithmator followed by an analog/digital converter. Monolithic integration of the circuit appears to be possible.
Patent DE-3830585-A1 (DE)
Title: Coupling unit for optical waveguide connectors
Inventor: MONAT HERMANN DIPL ING
IPC: G02B6/38
Filed: 1988-09-08
Abstract: The connector pins (3, 4) of the optical waveguide connectors (1, 2) to be connected to one another are guided together in a catch spring (loop spring, grid spring) (11). This helical spring is located in a guide sleeve (10) of a housing (7, 8) and is arranged there so as to align to the longitudinal axis of the optical fibre connector pins (3, 4); the housing simultaneously serves to receive and guide the connector pins. The connector pins are inserted into the widened catch spring from the two sides and aligned therein and held in a force-fitting manner when the spring narrows (constricts). The great advantage of the coupling unit according to the invention consists in that the connector pins have to be inserted into the coupling unit only with a plug force which is negligible and in that subsequently the connector pins are aligned with high precision when the catch spring narrows. This makes it possible to use connector pins which are resilient in the axial direction and only have a limited spring force, thus excluding possible damages of the connector end surfaces, and to combine a plurality of spatially adjoining optical waveguide connectors to form a multiple connector. The catch springs which are assigned to the associated individual coupling units are then in each case jointly opened and closed by means of a suitable drive. <IMAGE>
Patent DE-3840472-A1 (DE)
Title: Sliding surface components for endoprostheses
Inventor: LIEKE MICHAEL DIPL ING DR
IPC: A61F2/38
Filed: 1988-12-01
Abstract: The invention relates to sliding surface components of endoprostheses, preferably intended for hip joint and knee joint endoprostheses, comprising sliding surface sections, elastic damping elements and shock-absorbing resilient elements, respectively, and support members. The conventional sliding surface components, e.g. for the knee or hip joint, are predominantly made of relatively hard materials. As a rule, one section is made of a plastic and the other section is made of metal or ceramics. Punctiform load peaks lead to local overloading which results in material destruction, as a rule of the softer (plastic) material. The destruction of sliding surface sections is to be prevented by avoiding the punctiform load peaks. According to the invention, this is achieved in that the punctiform forces are distributed over a large surface area, so that the load peaks are - at least largely - eliminated, and in that the load peaks are additionally eliminated by optimised shock-absorbing resilient elements and elastic damping elements, respectively. Technically, the solution is achieved according to the invention in that the sliding surfaces can be slightly depressed in a reversible and elastically damped manner (Fig. 2), so that the prosthetic component resting thereon has a larger support surface (Fig. 2). <IMAGE>

Patent DE-3908204-A1 (DE)
Title: Method for determining a gas temperature in an internal combustion engine
Inventor: BRONKAL BERNHARD DIPL ING
IPC: F02D41/24
Filed: 1989-03-14
Abstract: It is possible to measure the different temperatures of fresh air and intake air in an internal combustion engine with intake air preheating using a single temperature sensor which is arranged in the flow of intake air by proceeding as follows. At predetermined times the addition of hot air to the fresh air is interrupted and the temperature prevailing at the temperature sensor location is again measured. The rate of change of the temperature is calculated from the difference in temperature between two measuring times. A check is performed on whether the said rate of change attains or falls short of a certain limit. As soon as this condition is met, it is assumed that the measured temperature essentially corresponds to the fresh air temperature. The fresh air temperature having been determined in this way, the addition of hot air is permitted again. <IMAGE>
